Yellow Toner Life End message so I replaced it with a new cartridge, and I still have the same message. What do I do?

SOURCE: MFC 8460N giving Toner Life End message

I just solved my own problem. Try it for yours. I had been using several compatible toners for the MFC-8460N with no problems until today, as I posted earlier. On a hunch, I went to the local office supply store and purchased one original Brothers TN550 toner and put it into the printer and closed the cover. Everything clicked. Toner End Life message gone. I then took that Brother toner out and put the compatible one back in and still everything was fine. Am keeping the original Brother toner as a "kickstarter" if it happens again.

Hi

Just cover the eyes (on both sides) that you can see in the bottom of the machine after removing the imaging cartrige with a small piece of electrical tape.

With printer switched on push the switch which is located inside the upper left side of printer (it is a small white switch) and then release it. 


Also try resetting the gear, take the cartridge out. On the gear side take off 2 screws, the black gear on top right side, with a small spring underneath. Just take it off and reset it (rotate clockwise) so it is not at the stopping point.

Please do accept this solution and revert for further assistance.

Thanks

You could try resetting the toner cartridge settings. OPen the machines front door where you would replace the cartridges. On the top panel you will see a "clear/back" button. Press it and on the display you will see a reset menu come up. Arrow to each one and hit the OK button. Press "1" to reset. Once you have gone through all close the front door of the machine and press stop to bring the display back to normal.

Hope this helps.
